Repeart控件中嵌套DataList控件
Repeart控件中嵌套DataList控件,一般显示数据,网页上都比较喜欢用Datalist因为他很灵活,而且样式好控制.而一些特定的功能需要用到数据控件之间绑定才能实现.但如果在DATALIST中再绑定一个DATALIST呢?这样效率很底.在功能条件允许的情况下,应该更优先的考虑REPERT很DATALIST的嵌套.
下面是我写的一个Repeart控件中嵌套DataList控件例子
test.aspx
<div>
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<ItemTemplate>
<li style="color:Blue;"><%#DataBinder.Eval(Container.DataItem,"name") %></li>
<asp:DataList ID="DataList1" runat="server">
<ItemTemplate>
<li style="padding-left:30px; color:Red;"><%#DataBinder.Eval(Container.DataItem,"title") %></li>
</ItemTemplate>
</asp:DataList>
</ItemTemplate>
</asp:Repeater>
</div>
test.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
string sql="select * from nvwa_type order by id";
string connstring="Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+Server.MapPath("~/App_Data/mydate.mdb");
OleDbDataAdapter oda= new OleDbDataAdapter(sql,connstring);
DataSet ds=new DataSet();
oda.Fill(ds);
this.Repeater1.DataSource = ds;
this.Repeater1.DataBind();
}
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
string connstring = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("~/App_Data/mydate.mdb");
int type_id = Convert.ToInt32(((DataRowView)e.Item.DataItem).Row["id"].ToString());
DataList dl = (DataList)e.Item.FindControl("DataList1"); //找到DataList1控件
if (type_id != 0 && type_id != null)
{
string sql_p = "select * from nvwa_product where type=" + type_id + " order by id";
OleDbDataAdapter oda = new OleDbDataAdapter(sql_p, connstring);
DataSet ds = new DataSet();
oda.Fill(ds);
dl.DataSource = ds;
dl.DataBind();
}
